| 1 | SPH modeling of fluid-structure interaction显示文摘This work concerns numerical modeling of fluid-structure interaction(FSI) problems in a uniform smoothed particle hydrodynamics(SPH) framework. It combines a transport-velocity SPH scheme, advancing fluid motions, with a total Lagrangian SPH formulation dealing with the structure deformations. Since both fluid and solid governing equations are solved in SPH framework, while coupling becomes straightforward, the momentum conservation of the FSI system is satisfied strictly. A well-known FSI benchmark test case has been performed to validate the modeling and to demonstrate its potential. | Luhui Han Xiangyu Hu | 2018 | Journal of Hydrodynamics2018，30，1： | 7 |
| 2 | 热带森林优势种青冈叶片气孔、解剖和形态性状与气候、土壤因子的关联显示文摘了解优势树种叶片多水平的功能性状沿海拔梯度的变化及其内在关联,有助于预测优势种应对气候变化的响应与适应。本文研究了青冈属树种叶片气孔、解剖和形态性状沿海拔梯度的变化及其与环境调控因子的关联,探究了其生态策略是否随海拔发生改变。在海南尖峰岭热带森林,沿海拔梯度(400–1400 m)采集了6种常绿青冈:竹叶青冈(Cyclobalanopsis bambusaefolia)、雷公青冈(C.hui)、托盘青冈(C.patelliformis)、饭甄青冈(C.fleuryi)、吊罗山青冈(C.tiaoloshanica)和亮叶青冈(C.phanera)叶片,用于气孔、解剖和形态性状的测定。研究结果表明,随海拔升高,青冈树种叶片气孔密度、气孔孔隙度指数和叶面积显著增加,但海绵组织厚度比和干物质含量则显着降低。叶片气孔、解剖和形态性状沿海拔梯度的变化主要受年均温、年降水量和土壤pH值调控。在低海拔和高海拔处,青冈属采取“耐受”和“竞争”策略,而在中海拔处,则是“竞争”策略。土壤磷含量和土壤pH值随海拔的变化可能是驱动其生态策略转变的主要原因。该结果揭示,热带森林优势树种青冈可通过从气孔细胞-组织解剖结构-叶片水平功能性状的改变来响应环境变化。 | Yutong Lin Luhui Kuang Songbo Tang Zhijian Mou Oliver LPhillips Hans Lambers Zhanfeng Liu Jordi Sardans Josep Penelas Yuan Lai Mingxian Lin Dexiang Chen Yuanwen Kuang | 2021 | Journal of Plant Ecology2021，14，6： | 0 |
| 3 | Mechanistic investigation on Ag-Cu_(2)O in electrocatalytic CO_(2) to CH_(4) by in situ/operando spectroscopic and theoretical analysis显示文摘Silver-copper electrocatalysts have demonstrated effectively catalytic performance in electroreduction CO_(2) toward CH_(4),yet a revealing insight into the reaction pathway and mechanism has remained elusive.Herein,we construct chemically bonded Ag-Cu_(2)O boundaries,in which the complete reduction of Cu_(2)O to Cu has been strongly impeded owing to the presence of surface Ag shell.The interfacial confinement effect helps to maintain Cu^(+)sites at the Ag-Cu_(2)O boundaries.Using in situ/operando spectroscopy and theoretical simulations,it is revealed that CO_(2) is enriched at the Ag-Cu_(2)O boundaries due to the enhanced physisorption and chemisorption to CO_(2),activating CO_(2) to form the stable intermediate^(*)CO.The boundaries between Ag shell and the Cu_(2)O mediate local^(*)CO coverage and promote^(*)CHO intermediate formation,consequently facilitating CO_(2)-to-CH_(4) conversion.This work not only reveals the structure-activity relationships but also offers insights into the reaction mechanism on Ag-Cu catalysts for efficient electrocatalytic CO_(2) reduction. | Min Sun Luxiao Zhang Fuli Tian Jiaxin Li Yanqiu Lei Heng Zhang Lifeng Han Zhihua Guo Yonghui Gao Fenrong Liu Yan Wang Luhui Wang Shanghong Zeng | 2024 | Journal of Energy Chemistry2024，88，1： | 0 |
